Nope 

the CAPS LOCK button on the keyboard

I'm sorry I laughed at this one.  Made my day.

But there are exceptions - Amortization for example on Sch E transferring in from fixed assets or fixed asset manager will only print in lower case. Pisses me off that the entire return is upper case but this one line.

But why do so many people want to print in all caps anyway?  Aren't you afraid that the IRS is going to think that you are shouting at them? 😁
